Title (EN) DELIVERY SYSTEM AND METHODS FOR RESHAPING A HEART VALVE ANNULUS, INCLUDING THE USE OF MAGNETIC TOOLS
(FR) SYSTÈME D'ADMINISTRATION ET PROCÉDÉS DE REMODELAGE D'UN ANNEAU DE VALVULE CARDIAQUE, COMPRENANT L'UTILISATION D'OUTILS MAGNÉTIQUES
Abstract:
(EN) Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.
(FR) L'invention concerne des systèmes et procédés d'administration et des dispositifs associés pour faciliter l'administration et le déploiement d'un implant cardiaque. De tels systèmes et procédés d'administration comprennent l'utilisation d'une paire de cathéters magnétiques, comprenant un cathéter d'administration d'ancrage portant un ancrage, qui peut être empilé sur la tête magnétique ou être décalé axialement de celle-ci. De tels systèmes comprennent en outre l'utilisation d'un fil-guide de perforation pouvant avancer à travers la tête magnétique du cathéter d'administration d'ancrage pour établir un accès à une chambre d'un coeur et qui est fixé à un élément de pontage de telle sorte qu'une progression continue du fil-guide tire un élément de pontage fixé au premier ancrage à travers la chambre du coeur tandis que l'élément de pontage reste recouvert par les cathéters couplés magnétiquement. L'invention concerne également des procédés et des dispositifs permettant de couper et de retirer un élément pont d'un implant cardiaque déployé.
